Hmm. Not sure this is right, but I'm giving it a try. Recognize closed
paths and attempt to construct two disjoint paths as their convolution
with the pen. This appears to break when the path has a radius of
curvature smaller than the radius of the pen. I'm committing it to CVS
mostly so I don't lose the code; I will shortly commit a patch which
eliminates the check for a closed path.
Oh, one correct change is to _twin_path_leftpoint which used to try to be
clever about point selection. Now that pens are forced to be convex,
the correct point to use is the one furthest from the line.
Ignore subpaths containing a single point. Add 'twin_path_append' to glue
one path into another.
Add debug output that shows vertices of polygons
Code to test convolution change mentioned above
